Markets: Stocks dipped modestly at the open following the weekly jobless claims report that showed the four-week moving average rose to its highest since January and after a handful of earnings news that disappointed.

Earnings: TriQuint Semiconductor spooked investors with a warning that it faces a "challenging" quarter, and the Hillsboro communication chip company forecast a sharp -- albeit temporary -- drop in revenues.
